Refresh update panel when database changes

I have an admin page in which I need to change the list whenever a user signs up on our web site.How can I put and event to MySql database so that whenever the count of a table row changes it refreshes my update panel for me to see the new user.

I for a page with multiple update panel in parent page, I got a button that will open a child window, after I close the child window, how can I refresh the parent page? And I only want to refresh a single update panel section instead of all other update panel section.

I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.

Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)

I have found an odd bug in my application. I have a dropdown status which is bound to my gridview. On selecting a status from the dropdown the selectedindex then fires and binds the results to the gridview.

Now the strange behaviour in firefox and not IE:

If I have a dropdown open and an ajax update fires on my gridview the option is selected from the dropdown (just by hovering my mouse over it rather than selecting it) and the results bound to the gridview. This does not happen in ie as you should have to physically select an item from the dropdown rather than firefox selecting it for you because you happened to hover over an option when the update event fires.

I have an accordion control in my web site. And in one of the panels, I have a drop down list box where, when the user selects an item, it updates the labels right below the ddlistbox. I have it so that it maintains the scroll position when the ddlistbox has an autopostback, but it's very obvious that the whole page posts back.

My question is, can I/should I just enclose the ddlistbox and the labels (and a couple of text boxes) in an AJAX update panel? I already have a ToolScriptManager (because of the accordion control), so I don't need to have another script manager, right? I can just put the update panel (with the other controls inside of it) right in the accordion panel, right? Then when the ddlistbox posts back it won't have the delay of the whole page posting back? And it'll still execute the event handler for the listbox selection change?

Does this sound right? I'm just looking to make the post back "invisible", and I would like to do a partial postback of just these few controls.

Hi everybody. Heres the deal. I have a three step Wizard with various textboxes in it. I out the Wizard inside an Update Panel and Content Template. I launch the site and the first step of the wizard is executed nicely but when I click next to get to the second step, nothing happen. If I take the wizard out of the update panel then it works fine.

Any help would be very much appreciated cause I am a bit new in ASP.NET.

I have a recursive sub that finds a dropdown list and sets up an AsyncPostbackTrigger for an update panel. I have tried calling this sub both from page_init and page_load

If the dropdownlist is within the update panel, eveything works fine. If the dropdown list is not in the updatepanel I get error

A control with ID 'ddlPersonFilter' could not be found for the trigger in UpdatePanel 'up1'. In both cases the sub does find the dropdown list and executes the code to set up the trigger. Thanks for your help.

Private Sub SetUpdatePanelTrigger(ByVal oControl As Control)
For Each ctrl As Control In oControl.Controls
If TypeOf ctrl Is DropDownList Then
If CType(ctrl, DropDownList).ID = "ddlPersonFilter" Then
Dim thisddl As New DropDownList
Dim thistrigger As New AsyncPostBackTrigger
thisddl = ctrl
thistrigger.EventName = "SelectedIndexChanged"
thistrigger.ControlID = thisddl.ID
up1.Triggers.Add(thistrigger)
Exit Sub
End If
Else
If ctrl.HasControls Then
SetUpdatePanelTrigger(ctrl)
End If
End If
Next

the app I am working with is made up of three nested master pages that have the following design:

The first master page ha only realize the HEADER, BODY and FOOTER divs.

The second one specialize the Body content placeholder and divide it in three more layers: NAVIGATOR, PAGE TITLE, BODY CONTENT.

The final layer specialize the BODY CONTENT in PAGE CONTENT and ACTIONS.

In one of my content pages I have (inside the PAGE CONTENT area)

1 Update Panel that contains a gridview object

1 Update Panel that contains some HTML code to show in a PopupModalExtender

The PopupModalExtender can be either triggered from inside the gridView and also from a series of LinkButtons that are in the ACTIONS area.

The problem is that when the PopupModalExtender shows the FOOTER and the ACTIONS areas are not dimmed from the style I apply as background to the modal popup. An example of what I am trying to explain can be viewed in the following screenshot.

Why this is going to happen? Has anybody any suggestion on how to solve this problem?

I have a page with a TabContainer with 3 tabs. Within each tab, I have an UpdatePanel. One of my UpdatePanel's update mode is set to "conditional" and I've added an asyncpostbacktrigger with the controlId="btnClearEmail1" and the eventname="Click". When I run the page and click the button assigned to the asyncpostback trigger, the page will do a full postback. Am I forgetting something? How can I get it to just refresh what is inside the UpdatePanel?
